Hi, ive got limited experience of adwords and been asked to take over an account thats been running for a long time. so far ive dropped the broad match terms in favour of exact match and phrase matched variations i know drive sales from google analytics data ive trimmed all the terms that have a high cost of aquisition this has improved the campaign so instead of making a few hundred pounds a month its doing around 30k. all positions are top ive still got money in my daily budget but dont know what do do from here. anyone got any adviice or some reading material?
